5005 Praxis Practice Test Practice Question
The preceding food web represents the feeding relationships in a certain ecosystem. Based on the food web, an increase in the population size of the grasshoppers will most likely result in an increase in the population size of which of the following?
Correct Answer: D
Rationale: An increase in the grasshopper population provides more food for predators, particularly owls, leading to a potential rise in their numbers.
Option A, the grasses, would likely decrease due to more grasshoppers consuming them. Option B, the rabbits, may not see an increase as they compete with grasshoppers for food; their population could remain stable or decline. Option C, the foxes, although they may benefit indirectly from increased prey, are not the primary consumers of grasshoppers and thus would not see a direct population increase. Hence, owls are the most likely beneficiaries in this scenario.
